Although these are the allowable frequency ranges, do not violate the VCO frequency range of the PLL. See the
MCF5227x Reference Manual for more details.
The minimum system frequency is the minimum input clock divided by the maximum low-power divider
(16 MHz ÷ 32,768). When the PLL is enabled, the minimum system frequency (f
This parameter is guaranteed by characterization before qualification rather than 100% tested. Applies to external clock
reference only.
Proper PC board layout procedures must be followed to achieve specifications.
This parameter is guaranteed by design rather than 100% tested.
This specification is the PLL lock time only and does not include oscillator start-up time..
